Injuries and illnesses can greatly affect how your nerves function, which is why we may include EMG/NCV testing as part of your diagnosis.

How does EMG/NCV work? Used to record the electrical activity of your peripheral nerves and muscles, electromyography (EMG) can detect neuromuscular disorders that affect skeletal muscle fibers, nerve impulses to the muscles and central nervous system, and voluntary muscle reflex activity. Nerve conduction velocity (NCV) can detect nerve compression or trauma by evaluating the speed of the conduction of motor and sensory fibers in the peripheral nerves.

With EMG/NCV testing, we are able to assess the condition of your nerves and muscles and to check for damage. If any abnormalities are found, we can even gauge the severity and extent.

What to expect during the procedures. The entire test will take 20 – 45 minutes. For the NCV test, recording electrodes are taped to a particular nerve area like your arms, legs, hands or feet. A stimulating electrode is then placed over the nerve which sends a very small electrical current.

For the EMG test, very fine needles are inserted into the muscles of your limbs and possibly your neck or back. These electrodes record your muscle's electrical activity during periods of activity and rest.

Are these tests painful? While some parts of the EMG/NCV may be uncomfortable, they are tolerated quite well. You may experience mild muscle soreness for a day or two after the test.

Will any of my medications interfere with the test? If you are taking any blood thinners such as aspirin or Coumadin, please inform your doctor. Since blood thinners can increase your risk of bleeding or bruising, your doctor may suggest not taking this type of medication until after the procedure. All other medications are fine and should be taken.
